...but this does not do anything.

The snippet you have doesn't generate any output, so how do you tell?

That said, it certainly won't play the wave file... because the module is solely for reading/writing (manipulating) wave files.

On Ubuntu, with the Alsa sound system, you have a great utility called aplay. It will auto-detect the soundfile stats, for proper playing, so all you need to play a wav is

#!/usr/bin/perl

# fork off, so the playback is non-blocking
if(fork() == 0){exec("aplay $my_sound_file")}

Or with Perl......

#!/usr/bin/perl
use warnings;
use strict;
use Audio::DSP;
#alsamixer must be setup right, just turn everything up :-)

#  use the channel count, bitrate, and samplerate of the wave 
#  you want to play
my ($buf, $chan, $fmt, $rate) = (4096, 1, 8, 22050);

my $dsp = new Audio::DSP(buffer   => $buf,
                      channels => $chan,
                      format   => $fmt,
                      rate     => $rate);
$dsp->init() || die $dsp->errstr();

my $file = shift || 'Om.wav';

open(IN, "<$file") or warn $!;
while ( 4096 == read( IN, my $buffer, 4096 ) ) {
    $dsp->dwrite($buffer);
}

$dsp->close();

That library is for reading raw data from wav files. It is not for playing them.

In theory you could probably use it and another module that interfaces with your sound card such as Audio::DSP, but unless this is some sort of learning project or your needs are complex or unusual, then that would probably be to much work.

Instead I suggest you check out the many Linux applications out there for playing multimedia. If it where me I would start with mplayer or perhaps ffplay (part of ffmpeg), as they both have simple command line interfaces.
